I have made my own test environment and I am having problems with pinging other servers from one server. All servers can ping to domain controllers and they get responded back. When I ping from a server to another server, I get following message "Destination host unreachable." Running Windows Server 2012 R2 all on servers and DCs
They all have static IPs

Check to make sure all systems are listed properly in DNS. For your DC follow this, or check your install against it.

We typically assume that if you don't mention the version of OS your using the most current, if not don't forget to mention the version (2005/2008/2012) you'll get more specific answers that way.
ALSO check your hosts files: C:\windows\system32\drivers\etc\hosts The best way to find this is windows explorer and type the path, the etc folder is typically hidden.
